WATER-GAGE.V

i To all whom t may concern i citizen of the United States,

Be it -known that I, JAMES' E. CUNLIFF, a residing at No. 1902 Bailey avenue,in the city of Buffalo,

in the county of Erie and State of New York, have invented certain new and useful Improvements in Water-Gages, of which the followings a specification.

My invention 'relates to improvements in water-gages for use upon boilers of railroad locomotives land stationary engines and the objects of my invention are :I First To eliminate all .possibility of injury to the person,'and especially to the eye-sight vof those persons, who, by the very natureof their occupation., are in continual proximity to the water-'gage on boilers. Second z-To provide an arrangement, wherein a strong outer glass, will take the place of the inner, or waterfglass proper, when the latter breaks. I attain these objects by the mechanism i11us trated in the accompanying rawings, one of which shows a combination water-gage, having three sides, while the other drawing shows a similar gage with four side's.

tov similar parts l' l tion to Figs. l, 2, and 3, with similar let- Similar letters refer throughout the drawings.

Figure 1, is an elevation of a three sided' water-gage. Fig. 2, isda lvertical section of the upper part the center line. Fig. 3, is a horizontal section through the middle of the gage on lthe lines Z-Z, of Fig. 1. Fig. 4C, is an elevation of one of thel transparent glass panels showing the web around its entire surface. Fig. 5, is an 'elevation' of a four sided watergage. Fig. 6, is a'vertical section of the upper part oi the said Water-gage on the centerline. Fig. 7, is a horizontal section through the middle of the gage, on the lines Z,Z,o,Fig-5 llnFig'. l, A, is the body of the waterigage comprised of a single piece :of material, through lwhich the water-glass E passes 'orming a `chamber between the outside of the water-glass E, and the inner portion of the body A, and the panels C, G. v The waterglass E, is supported at the top and bottom of said body by the coupling-nuts Di, D. rlhe top and bottom ofthe body A, are'circular-in form, and have outsidethreads to receive the coupling nuts D, D'. f B, B, B, areyplates holding the panels C,:C, C, .said plates being attached' to the body A, by means of screws a, a, etc., and vforming outside anges to engage with the packing c, o

.and the plates B, B, and B. "F cock, screwed into -body A,

side threaded at' each' end. A'are' packings made of suitable material, for

of the said water-gage pn' which in turn engage with the packing d, d,

-etc. on the inside ,liang'es of the body A.

The panels C, C, C, are made of glass or similar transparent material, and are of extra thickness as shown, and are provided with a web for engaging packing d al etc.. on the inside flanges on the` body Aand on the outside with the packing c, o, etc., is a vent the lower portion of the and communicates with the said chamber as shown more particularly in Fig. .I b, is a packing in thecoupling nut D, for making a steam and water tight joint between the water-glass E, and the coupling vllatented J une il, 11915..'

nut D. The lower coupling nut D, is pro- 1 vided with a similar packing b, (not shown on drawing). Coupling nuts D, D, have a flange in the center, as shown, and are inc, c, etc., and d,

the purpose of making steamand water tight Joints between the body A, the panels VC, C, C, and the lates B, B, B. Y Figs. 5, 6, and are similar in constructers; except thatthe body has four sides, four panels, and four glass plates. As rlong as the tube E, thus contained in the-body A, remains unbroken, the body A., withl the glass panels C, C, 6 incased in its sides, serves merely as a shield about the water tube E. 'But as soon as the tube E breaks, the water, condensed steam, and powdered glass, escape through the vent cock F," inserted in the lower portion of the body A, between two of its sides. By then closing F, the body A, becomes a perfect water-glass, since the fragments of the broken tube E, that remain in the chamber within the body A, in no way interfere with the water re`1 maining at its true level in the body A.

While the' body A, could be used as a water-glass as well, independently of the tube E, asc in combination with it, still, it is the' intention, in combining them both here,

that the body A, shall serve ymerely as a shield to the tube E, as

long as the latter remains unbroken, and be used as a waterglass, only in cases of emergency, as for instance when the tube E, breaks, while the Itt is understood that changes inithepre top and bottom of said bod ,to form a steam v and water tight chamber, r1n said body; and

closed can be made within the scope of the' following claims without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, of the United States of America, is:

1. In a means for protecting the ordinary water glass and forming a supplementary glass, the combination with said water glass of a metallic ,body provided with openings, transparent panels provided with webs Covering said openings in said body, flanges formed on said body and surrounding said openings, packing between the webs of said panels and said flanges, plates for holding the panels to said body and a packing between saidplates and the web of said panels, a coupling nut oneach end ofsaid body and a packing in said coupling nut for making a tight joint around said water glass.

f2. In a water-gage, the combination of a` metallic 'body composed of a single piece of material, said body having side openings, transparent panels covering side, openings,

a transparent tube passing through the center of said metallic body, couplings at the exterior to said tube, and means commumcatmg with said chamber, to indicate the j breakage of said tube and whereby: the contents of said chamber may be retained in the event of the Breaking of said tube. J

3. In a water-gage, the combination of a circular glass tube surrounded by a metallic body having glass sides attached thereto in u a steam' and water tight manner, and forming a chamber between said glass tube and said metallic body, said body provided witli a cylindrical neck at each en d, and having coupling nuts screwed over each of sald' necks, and into` each of which coupllngv nuts are fitted steam and water tightfgaskets, said metallic body being formed of a single piece of material, and having a vent valve in the lower portion of said body communicating with-said chamber.

4. In a water gage, the combinationof a permanent shield of refractory material provided with sight openings, transparent panels covering said openings and provided with webs around their outer edges, packing means between said webs and said shield, plates for holding said panels to said shield, packing meansbetween said plates and said webs, said shield adapted to be placed on an ordinary water glass which extends through said shieldv in such a. manner as to form a chamber between said shield and Asaid water glass, an opening in the base of said shieldv
